Remember
We in the West are living in the midst of a jihad, and most of us don’t even realize it — because it’s a brand of jihad that’s barely a generation old. Islam divides the world into two parts. The part governed by sharia, or Islamic law, is called the Dar al-Islam, or House of Submission. Everything else is the Dar al-Harb, or House of War. It’s called the House of War because it, too, according to the Koran, is destined to be governed by sharia, and it will take war — holy war, jihad — to bring it into the House of Submission.
— Bruce Bawer, Surrender (2009)
Note: While certainly no ally of traditionalists and conservatives, Bawer certainly got this right. But don't take his or my word for it, read it for yourself in Reliance of the Traveler, a classic interpretation of Sharia Law. I'm glad to lend my copy to the curious. Do the work. Read primary sources, not the news.
